BACKGROUND: In the treatment of terrible triad injury of the elbow (TTIE), the indication and the appropriate approach and sequence for coronoid process (CP) fixation remain debatable. No gold standard protocol has been established for CP fixation. In this study, we evaluated the midterm outcomes of coronoid-first repair through an anterior approach in patients with unstable TTIE. MATERIALS AND METHODS: This prospective observational study included patients with TTIE who exhibited posterior or posterolateral subluxation/dislocation during examination under anesthesia (EUA) at our institute between January 2019 and December 2021. All patients underwent coronoid-first repair through an anterior approach, regardless of fragment size. After CP fixation, radial head fixation/replacement and lateral ulnar collateral ligament repair were performed through the lateral Kocher approach. Radiographic and functional (Mayo Elbow Performance Score [MEPS] and Disabilities of Arm, Shoulder, and Hand score [DASH]) assessments were performed 3, 6, 12, and 24 months after surgery. Complications such as recurrent subluxation/dislocation, synostosis, heterotopic ossification, traumatic arthritis, and stiffness were examined at the follow-up visits. RESULTS: The analysis included 27 patients. The mean follow-up duration was 29.9 (range 24-44) months. At the 3-, 6-, 12-, and 24-month follow-up, the mean flexion-extension arcs were 88.7° ± 14.7°, 107.9° ± 11.9°, 128.3° ± 15.5°, and 130.9° ± 15.3°; the mean supination-pronation arcs were 143.7° ± 9.9°, 160.4° ± 7.6°, 165.0° ± 6.0°, and 167.9° ± 4.9°; the mean DASH scores were 18.7 ± 5.7, 4.5 ± 6.1, 2.7 ± 6.5, and 2.0 ± 6.8; and the mean MEPS were 79.1 ± 10.3, 90.2 ± 8.3, 94.8 ± 6.6, and 95.9 ± 5.7, respectively. At the 24-month follow-up, 26 patients had excellent and 1 patient had good results according to MEPS. Only one patient had a complication: they exhibited stiffness and did not have a 30-130° flexion-extension arc at 24 months postoperatively. CONCLUSIONS: The EUA findings, rather than fragment size alone, may be a good indicator of whether the CP needs to be repaired. Midterm follow-up results implied that coronoid-first repair through an anterior approach yields satisfactory functional outcomes with minimal complications. LEVEL OF EVIDENCE: Therapeutic level II.

PURPOSE: The role of admission blood indicators in patients with acute compartment syndrome (ACS) remains debated. Our primary purpose was to observe variations of admission blood indicators in patients with ACS, while our secondary goal was to explore potential biomarkers related to ACS. METHODS: We collected information on patients with tibial fracture between January 2013 and July 2023, and divided them into ACS and non-ACS groups. Propensity score matching (PSM) analysis was performed to lower the impact of potential confounding variables such as demographics and comorbidities. Admission blood indicators were analyzed using univariate, logistic regression, and receiver operating characteristic (ROC) curve analyses. Then, we established a nomogram prediction model by using R language software. RESULTS: After propensity PSM analysis, 127 patients were included in each group. Although numerous blood indicators were found to be relevant to ACS on univariate analysis, logistic regression analysis showed that monocytes (MON, p = 0.015), systemic immune-inflammation index (SII, p = 0.011), and creatine kinase myocardial band (CKMB, p < 0.0001) were risk factors for ACS. Furthermore, ROC curve analysis identified 0.79 × 10/L, 1082.55, and 20.99 U/L as the cut-off values to differentiate ACS patients from patients with tibial fracture. We also found that this combination had the highest diagnostic accuracy. Then, we constructed a nomogram prediction model with AUC of 0.869 for the prediction model, with good consistency in the correction curve and good clinical practicality by decision curve analysis. CONCLUSIONS: We found that the levels of MON, SII, and CKMB were related to ACS and may be potential biomarkers. We also identified their cut-off values to separate patients with ACS from those with tibial fracture, helping orthopedists promptly evaluate and take early measures. We established a nomogram prediction model that can efficiently predict ACS in patients with tibial fracture.

INTRODUCTION: This study investigated stem subsidence following primary total hip arthroplasty (THA) with a Corail stem in patients who underwent two-staged bilateral THA. The second outcome of interest was to investigate whether a specific single cortical bone contact point might reduce postoperative stem subsidence. METHODS: The present study was conducted following the STROBE guidelines. The records of patients who underwent THA between 2016 and 2023 were accessed. All patients who underwent two-staged bilateral THA were retrieved. The direct contact between the stem and the cortical bone was assessed at various points in the metaphysis and the distal portion of the stem (diaphysis) in both anteroposterior radiographs of the pelvis (medial and lateral bone contact) and a Lauenstein view of the hip (anterior and posterior bone contact). The following parameters were measured and compared to assess stem subsidence: distance from the proximal femur at the stem bone interface and the tip of the lesser trochanter (distance A); distance from the tip of the lesser trochanter and the tip of the femoral stem (distance B). RESULTS: In total, 250 patients were included, 45% (149 of 250 patients) were women and 61% (153 of 250 THAs) were implanted primarily on the right side. The mean age of patients at the time of the first THA was 64.3 ± 10.0 years and the mean body mass index (BMI) was 28.0 ± 4.9 kg/m. The mean length of the follow-up was 14.1 ± 10.8 months. The overall stem subsidence following THA was 2.8 ± 0.7 mm (P < 0.006). A direct cortical bone-implant contact did not exert a statistically significant difference in subsidence of the THA stem at the metaphysis and diaphysis (P > 0.5). Stem subsidence following THA with a collarless cementless Corail stem was approximately 2.8 mm at 14 months. CONCLUSIONS: Direct cortical bone contact of the stem at diaphysis and metaphysis seems not to influence stem subsidence following THA using the Corail stem.

INTRODUCTION: A number of studies have demonstrated a significant reduction of surgical time for robotically assisted surgery (RAS) total knee arthroplasty (TKA) after the learning curve between 6 and 43 cases. It is unknown if the logistics of RAS produce a longer total theatre time since published literature only reflects the surgical time. It is also unknown how RAS surgical and total theatre times compare with computer assisted surgery (CAS) TKA. METHODS: This is a prospective study of 524 consecutive patients undergoing a CAS or a RAS TKA using the same cementless implant. We recorded age, sex, body mass index (BMI), incision time of the first case, total surgical time, total theatre time, length of stay and 90-day complication and readmission rate. RESULTS: During the study period, 205 CAS and 199 RAS TKA were performed. There was no difference at baseline in age (p = 0.546), sex (p = 0.920) or BMI (p = 0.791). Surgical time for CAS was 78.3 (± 22.2) min and for RAS was 80.1 (± 25.7) min, p = 0.451. Total theatre time for CAS was 117.4 (± 27.8) min and 119.3 (± 30.7) min for RAS, p = 0.515. There was no difference in length of stay (p = 0.674), 90-day complication (p = 0.530) or readmission rate (p = 0.930). There was a difference in skin-incision average time for the first case (p = 0.022). CONCLUSIONS: Although theatre set-up for the first case is 5 min longer, RAS-TKA does not prolong the surgical time or total theatre time when compared with CAS-TKA. There was no reduction in case volume since the introduction of robotics. LEVEL OF EVIDENCE: III.

BACKGROUND: The pelvic and femoral morphology are associated with the occurrence of early periprosthetic femoral fractures (PFFs) in cementless total hip arthroplasty (THA). Differences exist depending on the performed approach and implanted stem design. Therefore, this study was conducted to analyze the pelvic and femoral morphology in cementless short stem THA via a minimally-invasive (MIS) anterolateral approach. METHODS: A retrospective, single-center, multi-surgeon, comparative propensity-score matched study of a cohort of 1826 short stem THAs was conducted. A total of 39 PFFs within the first 90 days after surgery was matched on a 2:1 ratio to non-fracture patients. The morphology of the proximal femur was analyzed with canal flare index (CFI), canal-calcar ratio (CCR), canal-bone ratio (CBR), morphological cortical index (MCI), and femoral cortical index (CI). The pelvic morphology was analyzed with ilium-ischial ratio (IR), distance anterior superior iliac spine to the tip of the greater trochanter (AGT). Both groups were analyzed regarding several parameters for femoral and pelvic morphology in non-parametric testing and univariate regression analysis. RESULTS: A significantly higher AGT was detected in the fracture group (104.5 mm ± 18 versus 97.4 mm ± 9.8; p = 0.016). All other femoral and pelvic parameters did not differ between both groups, also when compared depending on the Vancouver type of the PFF. CONCLUSIONS: The morphology of the proximal femur and the pelvis do not differ in several radiological parameters in patients sustaining a PFF in cementless short stem THA via an anterolateral approach compared with matched non-fracture group. The findings are controversial to other studies with different stem types and approaches. Future studies should focus on analyzing the influence of the pelvic geometry and the shape of the proximal femur in the occurrence of PFFs in different approaches with the same stem type and vice versa.

BACKGROUND: An umbrella review of meta-analyses was conducted to evaluate the use of platelet-rich plasma (PRP) in arthroscopic surgeries of rotator cuff injury. The effectiveness of leukocyte-poor PRP and leukocyte-rich PRP in the treatment of rotator cuff surgery was also compared. METHODS: Web of Science, Embase, PubMed/MEDLINE, and the Cochrane Library were searched from inception to May 2024. Literature screening, quality evaluation, and data extraction were performed according to the inclusion and exclusion criteria. The Jadad decision algorithm was used to ascertain which meta-analysis represented the best evidence. RESULTS: A total of 11 meta-analyses with evidence level ranging from level 1 to 2 were included in this umbrella review. Leukocyte-poor PRP was effective in reducing rotator cuff retear rates, alleviating pain, and increasing Constant scores compared with non-PRP treatments. However, it did not show improvement on the University of California Los Angeles (UCLA) score, the American Shoulder and Elbow Surgeons (ASES) score, and the Simple Shoulder Test (SST) compared with the non-PRP treatment group. Meanwhile, the leukocyte-rich PRP group improved the SST but showed no different results when compared with the non-PRP treatment group. CONCLUSION: Compared with no use of PRP, leukocyte-poor PRP was able to alleviate postoperative pain, reduce the retear rate, and improve the postoperative Constant score. Leukocyte-rich PRP could effectively enhance postoperative SST outcomes, leading to improvement of patient satisfaction and quality of life. Future researches should prioritize long-term follow-up studies and evaluate the durability of these results.

BACKGROUND: To assess the results after elbow arthroplasty it is essential to gather patient-reported outcome measures (PROMs). However, the acquisition of PROMs poses a challenge because of potential low literacy, lengthiness and diversity of questionnaires, and questionnaire fatigue. Instead of a questionnaire, patient-reported outcomes can be collected using a single assessment numeric evaluation (SANE), the subjective elbow value (SEV). The aim of this pilot study is to assess the correlation between the SEV and conventionally used patient reported outcome measures (PROMs) after elbow arthroplasty. MATERIALS AND METHODS: The SEV was added to our follow-up system in 2021, consisting of a scale from 0 to 10 in which the patients are asked to rate the overall functionality of their elbow, 0 corresponds to very poor functionality and 10 to a perfectly functional or healthy elbow. All patients who underwent elbow arthroplasty (total or radial head) and responded to the SEV question were retrospectively identified and included. The correlation between the SEV at the final follow-up and the Oxford Elbow Score (OES), and between the SEV and the Quick Disbailities of the Arm, Shoulder, and Hand (quickDASH) score was assessed using Pearson's r. RESULTS: In total, 82 patients responded to the SEV question and were included in the study, with a median follow-up of 5 years [interquartile range (IQR) 3-7]. Of these patients, 17 (21%) underwent radial head arthroplasty and 65 (79%) total elbow arthroplasty. The Pearson's r for the correlation between SEV and OES was 0.502 (p < 0.001) and between the SEV and the QuickDASH -0.537 (p < 0.001), which correspond to a moderate correlation. CONCLUSIONS: The SEV shows a moderate correlation with conventional PROMs, demonstrating its potential in simplifying the follow-up of elbow arthroplasty, possibly decreasing time, costs, and patients' questionnaire fatigue compared with conventional PROM questionnaires.

INTRODUCTION: The distal radius fracture is considered the most common fracture in humans. For fractures classified as Arbeitsgemeinschaft für Osteosynthese (AO) 23-C1 + C2, there is no consensus on treatment in older patients due to inconsistent study results. The aim of this study was to compare conservative and surgical treatment in relation to wrist function and satisfaction in patients older than 65 years. METHODS: In this prospective randomized clinical trial, patients aged older than 65 years who suffered an isolated AO-classified C1 or C2 distal radius fracture were randomized to surgical treatment using palmar plate osteosynthesis or conservative treatment. Patient-rated wrist evaluation (PRWE) score and disabilities of arm, shoulder, and hand (DASH) was assessed 3, 6 and 12 months post-interventionally. Satisfaction, range of motion (ROM) and pain scores were evaluated at 6 weeks and 3, 6 and 12 months post-interventionally. RESULTS: A total of 80 patients with a mean age of 77.3 years (± 6.1 years) in the conservative group and 72.5 years (± 5.3 years) in the surgery group were included. Both the PRWE score, and the DASH score showed a statistically significant difference between the two groups after 3 months, 6 months and 12 months (p < 0.001). Patients in the surgical cohort showed a statistically significant higher satisfaction at the 6-week, 6-month and 12-month follow-up (p < 0.001 6 weeks + 12 months; p = 0.004 6 months). CONCLUSION: In this prospective randomized study, surgical treatment proved to be superior to conservative treatment in terms of the primary outcome variable PRWE score. Satisfaction was significantly better in the surgical group.

PURPOSE: Severe open forearm fractures commonly involve segmental bone defects. Although several methods have been proposed to treat segmental bone defects with such fractures, research comparing the radiological and clinical outcomes of free vascularized fibular grafts (FVFG) and the Masquelet technique (MT) is rare. METHODS: Data on 43 patients with open forearm fractures and segmental bone defects treated surgically in our hospital from January 2005 to January 2021 were retrospectively analyzed, and these patients were divided into an FVFG group (18 cases) and an MT group (25 cases). Clinical and radiological evaluations were performed regularly, and the minimum follow-up was 18 months. RESULTS: All 43 patients were followed up for 18 to 190 months, with a mean of 46.93 months. The mean follow-up time was significantly longer in the FVFG group than in the MT group (p = 0.000). Bone healing time was 3-16 months, with a mean of 4.67 months. The QuickDASH score at the last follow-up was 0-38.6, with a mean of 17.71, and there was no statistically significant difference between the two groups. Operative time, hospital stay, and intraoperative bleeding for bone defect reconstruction were higher in the FVFG group compared to the MT group (p = 0.000), whereas the number of procedures was lower in the FVFG group than in the MT group (p = 0.035). CONCLUSIONS: FVFG and the MT showed satisfactory clinical results for segmental bone defects of the forearm. Compared with FVFG, the MT exhibited a lower operative time, hospital stay, and intraoperative bleeding. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: Recent literature has found a consensus in favor of conservative treatment for type II supracondylar humeral fractures (SCHF). This retrospective observational study compares the short- to medium-term functional outcomes of conservative versus surgical treatment in 31 patients with SCHF (Gartland II and III) to assess the potential superiority of one approach over the other. MATERIALS AND METHODS: Thirty-one pediatric patients treated for SCHF-19 classified as Gartland II and 12 as Gartland III-were assessed in our department. Eight patients underwent closed reduction and cast immobilization, 22 were treated with closed reduction and percutaneous pinning, and one underwent open reduction and internal fixation with plates. Clinical and functional data were collected during follow-up, including elbow and forearm range of motion (ROM), grip strength, carrying angle, Flynn's criteria, and Disabilities of the Arm, Shoulder, and Hand (DASH) score. RESULTS: The average follow-up was 3.3 years (± 1.4 years). All patients demonstrated good functional recovery. According to Flynn's criteria, 85% and 81% of the patients achieved a satisfactory outcome in elbow flexion and carrying angle, respectively. No cases of nerve injuries were reported. Four patients developed cubitus varus in the Gartland II group, which was treated with closed reduction and casting with the initial alignment maintained (without a loss of reduction during the first week). However, compared to this group that was conservatively treated, functional and clinical outcomes were significantly better in the group with SCHF Gartland II treated with reduction and pinning (p < 0.05). CONCLUSIONS: Although some recent studies have demonstrated positive outcomes with conservative treatment for both Gartland IIA and IIB fractures, the short- to medium-term functional results in our study emphasize that superior outcomes were obtained with surgical treatment for Gartland II fractures when compared to those treated conservatively. TRIAL REGISTRATION: This study was performed in line with the principles of the Declaration of Helsinki. Ethics approval was obtained from our institute's ethics committee (registry no. 3511). LEVEL OF EVIDENCE: Therapeutic level III.

With the rising prevalence of shoulder arthroplasty, the incidence of revision shoulder arthroplasty is also increasing. The complexity of these revision procedures poses significant challenges, with bone loss being a critical factor impacting treatment outcomes. Addressing substantial humeral bone defects is crucial for ensuring implant stability and functionality. A comprehensive literature review was conducted using PubMed, Medline, and Google Scholar to identify existing classification systems for proximal humeral bone loss in the context of revision shoulder arthroplasty. The study assessed the advantages and limitations of these classifications, using this information to propose a new diagnostic and therapeutic algorithm. Several classification systems for proximal humeral bone loss were identified. McLendon et al. classify proximal humeral bone loss based on a 5-cm bone loss threshold and suggest an allograft prosthesis composite for losses exceeding this limit. Boileau's system stratifies bone loss into four types based on the extent of loss, with specific recommendations for each category. The PHAROS classification provides a detailed anatomical assessment but lacks quantitative precision. The proposed PHBL-SCORe system offers a novel algorithm incorporating preoperative radiographic measurements to determine the percentage of bone loss and guide treatment options. Proximal humeral bone loss presents significant challenges in revision shoulder arthroplasty, necessitating precise preoperative planning and classification to guide surgical intervention. Existing classification systems provide valuable frameworks but often rely on average population values, neglecting individual anatomical variations. The proposed PHBL-SCORe system offers a patient-specific approach, improving the accuracy of bone loss assessment and optimizing treatment strategies. Implementing this classification in clinical practice could enhance surgical outcomes and reduce complications associated with rRSA (revision Reverse Shoulder arthroplasty). Further studies are required to validate this algorithm and explore its long-term efficacy in diverse patient populations.

BACKGROUND: Distal femoral fractures account for less than 1% of all fractures. The therapy of choice is usually surgical stabilization. Despite advances in implant development over the past few years, complication rate remains comparatively high. The aim of this study is to analyze our results with plate fixation of distal femoral fractures with a focus on complication and fracture healing rates. METHODS: In this retrospective cohort study, patients (> 18 years) with distal femoral fractures treated at an urban level I trauma center between 2015 and 2022 were analyzed. RESULTS: In total, 206 patients (167 female, 39 male) with an average age of 75 (SD 16) years were diagnosed with a fracture of the distal femur. One hundred fourteen of these patients were treated surgically by means of plate osteosynthesis. In 13 cases (11.41%), a revision procedure had to be performed. The indication for surgical revision was mechanical failure in eight cases (7.02%) and septic complication in five cases (4.39%). Periprosthetic fractures were more likely to cause complications overall (19.6% versus 4.76%) and further included all documented septic complications. The analysis of modifiable surgical factors in the context of plate osteosynthesis showed higher complication rates for cerclage in the fracture area compared with plate-only stabilizations (44.44% versus 22.22%). CONCLUSIONS: The data show an increased amount of revisions and a significantly higher number of septic complications in the treatment of periprosthetic fractures of the distal femur compared with non-periprosthetic fractures. The detected combination of plates together with cerclage was associated with higher complication rates. Level of evidence Level III retrospective comparative study.

BACKGROUND: Glenoid version is an important factor in the evaluation of shoulder stability and shoulder pathologies. However, there are neither established reference values nor known factors that influence the glenoid version, even though valid reference values are needed for diagnostic and orthopaedic surgery like corrective osteotomy and total or reverse shoulder arthroplasty (TSA/RSA). The aim of our population-based study was to identify factors influencing the glenoid version and to establish reference values from a large-scale population cohort. RESULTS: Our study explored the glenoid versions in a large sample representing the general adult population. We investigated 3004 participants in the population-based Study of Health in Pomerania (SHIP). Glenoid version was measured for both shoulders via magnetic resonance imaging (MRI). Associations with the glenoid version were calculated for sex, age, body height, body weight and BMI. The reference values for glenoid version in the central European population range between -9° and 7.5°, while multiple factors are associated with the glenoid version. CONCLUSION: To achieve a reliable interpretation prior to orthopaedic surgery, sex- and age-adjusted reference values are proposed.

BACKGROUND: Modular acetabular components for total hip arthroplasty (THA) provide intraoperative flexibility; however, polyethylene liner dissociation may occur. This study aimed to examine the incidence and causes of liner dissociation associated with a specific acetabular component design at a single centre. MATERIALS AND METHODS: A retrospective analysis of 7027 patients who underwent primary THA was performed to identify isolated liner dislocations. Patient demographics, clinical presentations, surgical and implant details, and both radiographic and computed tomography (CT) findings were analysed. Patients with liner dislocation were matched to a control group via 2:1 propensity score matching, and a logistic regression analysis was employed to identify associated risk factors. RESULTS: A total of 32 patients (0.45%) experienced liner dislocation at a mean 71.47 ± 60.10 months post surgery. Significant factors contributing to dislocations included the use of a conventional compared with a highly crosslinked polyethylene component (p = 0.049) and screw fixation (p = 0.028). Radiographic and CT analysis highlighted the importance of proper component orientation, revealing that patients experiencing dislocations demonstrated significantly lower acetabular cup anteversion angles (p = 0.001) compared with the control group. Impingement and malposition, identified in 41% and 47% of the cases, respectively, further underscored the multifactorial nature of dislocation risks. CONCLUSIONS: While the overall rate of polyethylene liner dislocation was low, the findings of this study highlight the importance of appropriate cup placement to decrease the risk of dissociation. It further substantiates the influence of impingement and malposition in liner displacement, with increased mechanical stress exerted on the locking mechanism under adverse conditions and the potential risk increase due to screw placement.

PURPOSE: The aim of this study was to quantify the prophylactic effect of high-dose gentamicin and clindamycin antibiotic-loaded bone cement (ALBC) during revision total hip (rTHA) or knee (rTKA) arthroplasty for aseptic reasons. The hypothesis was that the raw surgical site infection (SSI) rate is lower when this particular cement is used in comparison with cement loaded with standard-dose gentamicin during rTHA or rTKA for aseptic reasons. METHODS: This retrospective study included 290 consecutive patients undergoing aseptic rTHA or rTKA. Two consecutive cohorts were defined: the first (control group) involved 145 patients where ALBC with gentamicin only was used; the second (study group) involved 145 patients where ALBC with high-dose gentamicin and clindamycin was used. The primary endpoint was the raw SSI rate after 24 months. RESULTS: The raw SSI rate was 8/145 (6%) in the control group and 13/145 (9%) in the study group (odds ratio 0.62, p = 0.26). There was a significant impact of the presence of any risk factor on the SSI rate (15/100 versus 6/169, odds ratio = 4.25, p = 0.002), but no significant impact of any individual risk factor. No complication or side effect related to ALBC was observed in either group. CONCLUSION: These results do not support the routine use of gentamicin and clindamycin ALBC for fixation of revision implants after rTHA and rTKA for aseptic reasons.

BACKGROUND: Anterior cruciate ligament (ACL) injuries are common among physically active individuals, and obesity may increase the risk of such injuries due to factors like biomechanical stress on the knee. We aimed to determine if obesity affects postoperative outcomes after ACL reconstruction. METHODS: Data from adults aged 20 years and older with ACL injuries who underwent inpatient reconstruction from 2005 to 2018 were extracted from the United States (US) Nationwide Inpatient Sample (NIS) database. Patients were divided into two groups based on the presence of co-existing obesity, defined as a body mass index (BMI) ≥ 30 kg/m. Propensity-score matching (PSM) was employed to balance between-group differences. Associations between obesity and concomitant meniscus injury, length of stay (LOS), post-procedural complications, and non-routine discharge were examined using univariate and multivariable logistic and linear regressions. RESULTS: After PSM, data from 1323 patients (representing 6396 individuals in the US) were analyzed. Of these, 441 (33%) were classified as obese, while 882 (67%) were not obese. After adjustment, obesity was significantly associated with a longer LOS (adjusted beta (aBeta) = 0.32, 95% confidence interval (CI) 0.31-0.321) and an increased likelihood of non-routine discharge (adjusted OR (aOR) = 2.18, 95% CI 1.47-3.22). There were no significant associations between obesity and concomitant meniscus injury (aOR = 1.04, 95% CI 0.81-1.32) or post-procedural complications (aOR = 0.97, 95% CI 0.74-1.27). CONCLUSIONS: In patients undergoing ACL reconstruction in the US, obesity is independently associated with a longer LOS and a higher risk of non-routine discharge. Nevertheless, obesity does not appear to be associated with concomitant meniscus injury or post-procedural complications.
